Abstract

We point out that the quantum secret sharing (QSS) protocol proposed by Gao et al. [Chin. Phys. Lett. 29 (2012) 110305] has some defects. Thus, some strategies are given to mend them.

Abstract

The information leakage problem often exists in bidirectional quantum secure direct communication or quantum dialogue. In this work, we find that this problem also exists in the one-way quantum secure communication protocol [Chin. Phys. Lett. 32 (2015) 050301]. Specifically the first bit of every four-bit message block is leaked out without awareness. A way to improve the information leakage problem is given. [ABSTRACT FROM AUTHOR]
